You have reached the CCN Inventory Tool Detailed Insights Report.
Great News! This geography has available data.
Potential data availability within the Inventory Tool ranges from Tier I, Tier II, or Tier III Carbon stock estimates.
Tier I: Global sediment carbon stock estimates.
Tier II: Country- or territory-level sediment carbon stock estimates.
Tier III: Modeled country- or territory-level sediment carbon stock estimates.
This is a downloadable document which includes specific insights and more detailed analysis for a selected territory or country, including carbon stocks, emissions factors, and ecosystem wetland area for mangrove, marsh, and seagrass habitats. This report details information for the selected geography, Nigeria.

Featured in the inventory tool dashboard, below is a table of any available sediment carbon stock estimates for the selected geography, Nigeria, for mangrove, tidal marsh, and seagrass habitat.
| Continent | Region | Territory | Habitat | Area (hectares) | Mean Stock (Mg/ha) | Reporting Tier |
|---|---|---|---|---|---|---|
| Africa | Sub-Saharan Africa | Nigeria | mangrove | 696000 | 386 | Tier I |
| Africa | Sub-Saharan Africa | Nigeria | marsh | 2045 | 255 | Tier I |
| Africa | Sub-Saharan Africa | Nigeria | seagrass | 887700 | 108 | Tier I |
Total Carbon stock estimates were calculated for each geography in total, and for mangrove, tidal marsh, and seagrass habitats, if applicable. At this time total Carbon stock estimates for each country do not include seagrass estimates due to the lack of a global, transparent, and independently assessed seagrass habitat map. However, best available areas and stocks for Nigeria are explored in the following ‘Wetland Areas and Activities’ section.
We estimate that Nigeria contains approximately 269200000 megagrams per hectare (Mg/ha) soil carbon to a depth of 1 meter.
| Territory | Country | Habitat | Total Stock | Upper CI | Lower CI | Standard Error |
|---|---|---|---|---|---|---|
| Nigeria | Nigeria | mangrove | 268700000 | 313200000 | 224100000 | 23230000 |
| Nigeria | Nigeria | marsh | 521400 | 662100 | 380600 | 73310 |
| Nigeria | Nigeria | seagrass | 95870000 | NA | NA | NA |
This total estimate includes country-level mangrove carbon stock estimates, with a mean estimate of 268654000 megagrams per hectare (Mg/ha) soil carbon in mangrove habitats.
This total estimate includes country-level mangrove carbon stock estimates, with a mean estimate of 521356 megagrams per hectare (Mg/ha) soil carbon in tidal marsh habitats.
This total estimate includes country-level mangrove carbon stock estimates, with a mean estimate of 95900000 megagrams per hectare (Mg/ha) soil carbon in seagrass habitats.
We estimate mangrove area in Nigeria to be 611000 to 807000 hectares with a mean estimate of 696000 hectares according to Global Mangrove Watch, Bunting et al 2018.
We estimate tidal marsh area in Nigeria to be 1240 to 2310 hectares with a mean estimate of 2040 hectares according to Global Mangrove Watch, Bunting et al 2018.
We estimate seagrass area in Nigeria to have a mean estimate of 888000 hectares according to McKenzie et al 2020.
This section of the report details whether data is available to estimate Tier I, Tier II, or Tier III value estimates for tidal marsh, mangrove, and seagrass ecosystems in Nigeria.
If data for the selected country is available in the Coastal Carbon Atlas, we have applied a Tier II emission factor based on a simple average of country specific data queried from the Atlas.
Country-specific soil cores from Nigeria have not yet been included in the Coastal Carbon Atlas. In this case, we have instead applied the IPCC Tier I estimated value. IPCC Tier I estimates for mangrove, marsh, and seagrass habitats are listed below.
| Habitat | Mean | Lower CI | Upper CI |
|---|---|---|---|
| mangrove | 386 | 351 | 424 |
| marsh | 255 | 254 | 297 |
| seagrass | 108 | 84 | 139 |
Tier II, or territory-level carbon stocks were estimated, when available, from soil core data currently housed in the Coastal Carbon Atlas.
Territory-Level Data Availability for Nigeria: The selected geography, Nigeria does not currently have available Tier II carbon stock estimates at a depth of 1 meter. Please refer to IPCC global values.
Tier III, or modeled carbon stocks were estimated, when available, from remote sensing data from Maxwell et al 2021 for mangrove habitats, and Sanderman et al 2018 for tidal marsh habitats. The following details whether estimated values are available for Nigeria, and any overlap with associated Tier I or Tier II values.
If there are no modeled carbon stock estimates associated with the selected country, please refer to Tier I and/or Tier II tables.
Modeled Data Availability for Nigeria: There are currently no Tier III values for Nigeria in the CCN Inventory Dashboard. Please refer to IPCC global values.
